it's 100% rahab and medusa rematch in nutaku though, it's not the first time the change the order of events.
the rematch of garuda and typhon should have come after Xmas according to dmm but it's already done after yatagarasu event, isn't it?
they're doing it so halloween and Xmas events will start in their correct dates as there nutaku started 11 months after dmm and not 12, so it'll be funny to have halloween event in last week of september and Xmas event in november, right? so they're doing more events to fix it.
